Question

I want to write some notes in the draft of a LaTeX document, and at a later point I want to compile the document without them. I saw someone doing something like the following (but I forgot what he did). Write notes as {\scriptsize some_text}, and in the end replace all {\scriptsize ...} with {} with a \newcommand. But I can’t figure out how to write a \newcommand to replace all {\scriptsize some_text} occurrences by empty strings. I can then just comment or uncomment the \newcommand line.

Answer 1

Declare in the beginning of your file

\somevariabletrue
%\somevariablefalse

so you can quickly uncomment one and comment second, and in the later part of your code:

\ifsomevariable
  ...
\else
  ...
\fi
